NCV7705屬于集成電路（IC）的電機(jī)驅(qū)動器控制器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCV7705電機(jī)驅(qū)動器，控制器產(chǎn)品屬于電機(jī)驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實(shí)現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)載和預(yù)期應(yīng)用的特性有很大差異，范圍從用于有刷電機(jī)的簡單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級閉環(huán)運(yùn)動控制。

The NCV7705/NCV7706 is a powerful Driver?IC for automotive

body control systems. The IC is designed to control several loads in

the front door of a vehicle. The monolithic IC is able to control mirror

functions like mirror positioning, heating and folding. In addition,

NCV7706 includes the electro?chromic mirror feature. The device

features four high?side outputs to drive LEDs or incandescent bulbs

(up to 5/10 W). To allow maximum flexibility, all lighting outputs can

be PWM controlled thru PWM inputs (external signal source) or by an

internal programmable PWM generator unit. The

NCV7705/NCV7706 is controlled thru a 24 bit SPI interface with

in?frame response.
